| 黄河下游宽滩区既是大洪水行洪滞洪沉沙的通道，又是滩区群众赖以生存和发展的家园，如何合理运用宽滩区是长期备受关注和争议的话题。本文在水沙统筹、空间统筹和时间统筹原则的指导下，建立了黄河下游宽滩区滞洪沉沙功能与减灾效应二维评价指标体系，构建了基于Pareto最优解的黄河下游宽滩区滞洪沉沙功能与减灾效应二维评价模型，利用1958、1982、1992和1996年4场洪水实测资料，对该模型的合理性进行了验证。应用上述模型对黄河下游宽滩区不同运用方式的12组二维数学模型计算方案进行了评价，结果表明，洪水量级对减灾效应影响显著；相同洪水条件下设防护堤并控制闸门运用（有闸）或分区运用（5滩、10滩）方案能在滞洪沉沙功能和减灾效应之间取得更好的平衡，可作为未来滩区优化运用的决策参考。 |

| The wide floodplain of the Lower Yellow River(LYR) is a flood detention and sediment silting area, which is also the homeland of floodplain residents.How to utilize the wide floodplain is always a controversial topic for a long period. Based on the overall planning principles of water and sediment, wide floodplain and narrow reach, short term and long term, this paper has put up a comprehensive 2D evaluation index system, built a 2D evaluation model of flood detention & sediment silting and disaster alleviation effects in the wide floodplain area of LYR with Pareto optimal solution. The observing flood data of 1958, 1982, 1992 and 1996 were used to verify the model. Then 12 different floodplain utilization plans calculated by 2D numerical models were evaluated by the evaluation model above. The results show that the magnitude of flood affects disaster alleviation effects significantly; building dikes between two levees and using water-gate or divisional utilization plans will get a better balance between flood detention & sediment silting and disaster alleviation effects,which will be a reference for floodplain management in future. |
